摘要: Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.

摘要: Techniques enable building a collection of data that defines an asset, with the data possibly having differing data types. These techniques are then capable of assigning arbitrary policy to that asset, regardless of which data types are present within the asset. In addition, these techniques enable packaging of this first asset with one or more additional assets in a self-contained envelope. Each asset within the envelope may similarly include data of differing data types. Furthermore, each of these assets may be assigned a policy that may be different than the policy assigned to the first asset. This envelope, or a collection of envelopes, may then be provided to a content-consuming device to consume the assets in accordance with each asset's specified policy.

摘要翻译: 技术能够为数字内容创建预览许可。 在某些情况下,预览许可证表示允许内容消耗设备消耗的内容少于所有内容。 该预览许可证可以创建指定内容消费设备可能消耗的数字内容的多个部分的列表。 这些技术还可以向设备用户提供购买在消费预览许可部分之后消费所有数字内容的权利的提议。 在其他情况下,内容服务器可以将预览许可嵌入到包含数字内容的内容包中,允许服务器将包分发到多个设备。 在其他情况下,预览许可证可能会绑定到域而不是单个设备。 这允许成员设备共享数字内容和预览许可,使得每个成员设备可以享受预览体验。

摘要: This document describes tools capable of enabling cloud-based movable-component binding. The tools, in some embodiments, bind protected media content to a movable component in a mobile computing device in a cryptographically secure manner without requiring the movable component to perform a complex cryptographic function. By so doing the mobile computing device may request access to content and receive permission to use the content quickly and in a cryptographically robust way.

摘要: Systems, methods, and/or techniques (“tools”) for binding content licenses to portable storage devices are described. In connection with binding the content licenses to the portable storage devices (“stores”), a host may perform authentication protocols that include generating a nonce, sending the nonce to a store, and receiving a session key from the store, with the session key being generated using the nonce. The store may perform authentication protocols that include receiving the nonce from the host, generating a random session key based on the nonce, and sending the session key to the host.

摘要: Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.

摘要: Various embodiments utilize hardware-enforced boundaries to provide various aspects of digital rights management or DRM in an open computing environment. Against the backdrop of these hardware-enforced boundaries, DRM provisioning techniques are employed to provision such things as keys and DRM software code in a secure and robust way. Further, at least some embodiments utilize secure time provisioning techniques to provision time to the computing environment, as well as techniques that provide for robustly secure storage.
